At least in the GM world we can argue about tuning with the MAF or turning with the MAF off to perfect the VE tables.....My 'other' car, a SRT8, comes from Dodge with only Speed Density and a rediculous tune(11.3 : 1 or even richer in WOT)......Man, how I wish somebody could tune it. Thank goodness GM makes the coolest 2 seater(such that I can afford 
).

The car should be tuned for either SD or MAF, bottom line on both tunes... VE table should get tuned followed by the MAF recalibration if its a MAF car. Every car I tune we set base parameters, tune VE watching A/F and Knock(removing knock spots) Once the VE is dead on, turn the MAF on and tune the MAF.

tune it for max. perf. without the sensors, add the sensors back, tune the sensors to compliment the tune.
paint it with the tune, wax it with the sensors.

I'm not an "expert" but I do read a lot and I stayed at a Holiday Inn Express once or twice
I found this on LS1 Tech and it may answer some questions...
